To all 'whom t may concern:

Be it known that I, ANTONI IGNAToWsKI, a subject of the Czar of Russia, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Babbitting-Machines, of which the following is a specifica-A tion. V

The main objects of' this invention are to provide an improved machine adapted to hold railway journal box brasses when being lined with Babbitt metal; to provide in such a machine improved' means for positioning and holding the journal box brasses during the relining operation; to provide such a machine in which there are a plurality of adjustments so that brasses of varying sizes may be clamped therein; to provide a babbitting machine in which the mandrel may be shifted so as to utilize a maximum number of sections of the surface thereof; and to provide improved means in such a machine for guiding the molten metal into the space between the brass and mandrel.

An illustrative embodiment of this invention is shownin the accompanying drawings in which- Figure 1 is a top plan of a machine embodying four units. Fig. 2 is a transverse sectional elevation taken on the line AA,

Fig. 1. Fig. 3 is a section taken on the line.

B-B of Fig. 2. Fig. 4 is a front elevation of the left hand end of the machine shown in Fig, 1. Fig. 5 is an enlarged sectional detail taken on the line C--C of Fig. v4. Fig. 6 is a sectional detail taken on the line D-D of Fig. 2. Fig. 7 is a front elevation of the In the construction shown in the drawings the rectangular supporting framework comprises side frame members 1 and 2 and end pieces or members 3 and 4 secured together at their adjacent ends by any suitable means. The side frame members 1 and 2 are somewhat thickened at their middle portions so as to add strength and rigidity to the structure. Cross bars 5, 6, 7 and 8 are mounted on the side frame members andare adapted to provide supports for mandrels 9, 10, 11 and 12 which are secured thereon by bolts and nuts 13 and 14 respectively.

The mandrels are mounted vertically on the cross bars and are rotatably adjustable thereon.

Each of the mandrels is provided with a pair ofpositioning strips 15 which are vertically disposed along the sides of the mandrel and parallel to the axis thereof. Sockets 16 are provided on the outer sides of the strips substantially medially of the ends thereof. Adjustable clamps are provided for holding the strips tightly against the sides of the mandrel comprising a pair of jaws 17 and 18 pivoted together at 19. The free ends of the jaws have inwardly facing hooks 20 formed thereon which are adapted to fit in the sockets 16 of the positioning strips. The jaws 17 and 18 are provided near the base thereof with lugs 21 and 22 respectively to which are pivoted a pair of .and 30 respectively and which bear against the jaws 17 and 18 and press these jaws toward each other when the handles 25 and 26 are spread apart. g

The outer f nds of thevv handles 25 and 26 are embraced. between a pair o-f parallel members 31 and 32 which are held in spaced relation to each other by-blocks 33 interposed therebetween. The members 31 and 32 are sup orted above the rear side member 2 by vertlcally disposed braces 34 which have their upper and lower ends bolted toI the members and side frame respectively.

The units may be mounted in pairs as shown in Fig. 1 so that the adjacent handles may be yieldingly pulled toward each other by connecting them with a tension 'spring 35 and chain 36, the outer handles of each pair being held by the blocks 33 which are interposed between the members 31 and 32.

Each set of adjustable clamps is provided with means for preventing lateral shifting in a rearward direction comprising a bell crank lever 37v pivoted on the cross bar and mounted so as to rock on a vertical plane.

The arm 38 of the bell crank lever extends upward through a clip 39 which is secured* to the jaws 17 and 18 at their point of pivotal connection 19,- and the arm 40 extends rearwardly underneath the members 31 and 32 and is provided with a tension spring 41, the upper end of said sprin being provided with a threaded bolt 42 whic passes through a clip 43 secured on the upper surface of the member 32. Tension on the spring 41 is varied by a nut 44 threaded on the bolt 42.

Means are provided for holding the railway journal bearing brass 45 against the positioning strips and 16 and in spaced relation to the mandrels and comprise a standard 46 adjustably mounted on the cross bar and having an arm 47 pivoted thereon lat 48 and v a lever 49 pivoted to the upper end thereof at 50.l The base of the standard 46 is adjustable toward and away from the mandrel by means of set screw 51. The arm 47 is adapted to bear against the journal-bearing y v placedupon the mandrels and comprise po.-

si-tioning fingers 53 mounted on a rod 54 journaled in depending clips 55 .and 56 mounted on the end pieces 3 and 4 respectively. The rod 54 is rotatable and axially shiftable and one end thereof is pivoted to a handle 57- which extends' transversely across the end of the framework. The rear end 58 of the handle is adapted to slide in a vertically disposed slot 59 of a depending f bracket 60 mounted on the end piece 4 and the forward end 61 of thfe' handle is normally held in a horizontally disposed bracket 62 which is secured to `the side member 1. A'

pivoted latch 63 is adapted to normally hold the handle in the and 4. j f

Each of the mandrels is provided with a block 64 mounted on the top thereof which supports a vhorizontally dlsposed pin 65 which is threaded at its opposite lends to receive knurled nuts 66 andy 67. The nuts l66 and 67 each carry the upper ends of a pair of side plates 68 and 69 respectively which have a transversely disposed shelf 70 mounted therebetween. The shelf 70 is secuedto the side plates by means of bolts 71. and-72 "which pass through upstanding lugs73 and 74 on the shelf 70, said bolts passing out through the side plates and each having compression springs 75 and 76 mounted thereon between the side plates and nuts 77'l and 78 on the outer ends of the bolts.

The side plates 68 and 69 and the transversely disposed vshelf 70 form a gate which position shown in Figs. l

is adapted to be swung down as shown in full lines in Fig. 2 so that the side plates yieldingly embrace the opposite sides of the journal-bearing brass and the shelf 70 rests upon the top thereof as shown in Fig. 5. The shelf 70 slopes inwardly at 79 so as to guide the Babbitt metal into the space between the journal-bearing brass and the face of the mandrel.

A drip apron 80 is attached to and disposed underneath the front side of the frame -work so that any molten metal which may be spilled during the babbitting operation is caught by the apron and guided back underneath themachine and lis discharged into a drip box 8l.

The rectangular frame work is provided at its corners with short tapered legs 82 which are adapted to litl into the tops of a suitable tubular supporting stand 83 as shown in Fig. 7.

In the operation of the machine the railway journal-bearing brass is placed against the positioning strips which hold it in spaced relation to the mandrel and the arm 47 is clamped thereagainst by means ofthe lever l49, the correct position 'of the bottom ofthe journal-bearing brass being determined by the positioning linger53. The position of the strips 15 may be varied by means of the adjustable clamping mechanism so that bearing brasses of varying sizes may be lined on the same machine. Rearward movement of the strips when the brass is clamped thereagainst is prevented by the upstanding arm ,38 of the bell crank lever 37. The gate is then swung to the position shown in full lines in5 Fig. 2 so thatthe side plates embrace the opposite sides of the bearing brass and the transverse shelf is disposed immediately above the upper end of the brass. The Babbitt metal may then be poured onto the shelf`70 and is 'guided down into the space between the brass and the face of the mandrel, the side strips preventing any overf iow of the metal particularly in cases where the edges of the journal-bearing brass have been broken away during the casting or use thereof. With this arrangement the brass can be lined the entire length thereof. The gate is then swung back to the position shown by dotted lines in Fig. 2, the latch 63 is raised up and the handle 57 is shifted to face into position. It will thus be seen that practically four different sections of the mandrel surface may be utilized.

All of the clamping mechanisms, positioning fingers and gates are readily adjustable so that journal-bearing brasses -of varying sizes may be lined on this machine.

The dripping apron 80 catches any overflow of molten metal and keeps it from falling upon and burning the workman who is operating the machine.
